水布垭混凝土面板堆石坝填筑施工技术方案分析.docx

摘要
水布垭混凝土面板堆石坝是目前世界在建的最高面板堆石坝。由于受各种环境因素及内在施工环节相互制约的影响,使大坝的施工错综复杂。采用传统的方法或经验安排组织施工、选择施工设备带有一定的局限性。采用计算机模拟方法研究高土石坝施工中的问题, 可以较好地反映各因素作用下土石坝施工过程的动态变化,并得到定量的结果,以选定合理的施工组织措施,以确保工期和降低工程造价。
本文通过对面板堆石坝填筑施工系统的系统分析,明确了施工进度计划、场内交通运输系统情况、料场规划、建筑物开挖旌工、填筑麓工要求及机械设备等因素之间的相互关系,将施工进度与场内交通运输系统和坝面填筑系统有机结合起来。在论述了仿真技术原理的基础上,本文介绍了面向对象的模拟建模方法。面向对象技术是研究大型复杂系统的先进技术。本文运用面向对象技术建立了场内交通运输系统和坝面填筑系统模型,分析了两个系统的模拟原理和模拟方法。
运用计算机模拟技术,根据水布垭工程的施工组织设计资料,对水布垭工程进行了系统仿真计算。通过对不同方案仿真结果的分析比较,论证了该工程施工组织设计和进度规划的可行性和合理性, 确定了施工机械优化配置方案,对存在的问题也进行了分析,提出了一些合理的施工建议。

Shuibuya concrete face rockfill dam under construction i S the highest face rockfill dam in the world at con struction of dam plicated because of various envi ronmental facto rs and the inner interacting factors during the are some Iimitations in construction arrangement and equipment selection when the conventional method or experiment is adopted However in case that the simulating method is adopted,the dynamic change of the construction on which all kind of factors are acting can be reflected clearly and quantify solution i s gained through which reasonable measures 0f anization can be determined to ensure pletion and decrease the co st of the project.
Through systematic analysis on the construction system of face rockfill dam filling,the mutual relationship of the factors of construction progress schedule,access and transportation system on site,quarry planning,the requirement of excavation and filling of building structures,mechanical and electrical equipment are defined clearly and the construction progress,transportation system on site and the filling of dam face model building method of Methodology(OOM)as the advanced technology to study large plicated system i S introduced on the basis of demonstrated principle of applying OOM models 0f transDortation sy stem on site and filling system of dam face are establi shed and the principle and
